It looks like
geo-thermal heating and cooling is finally starting to show some progress here in the U.S. Iceland gets most of their energy from geothermal, of course. But it turns out that the U.S. has excellent geothermal resources as well, that we ought to be putting to better use.
My research on geothermal power plants has led me to conclude that this is a very promising investment sector and technology, and that geothermal heat exchange systems are great investments for homeowners as well.
I think I’ve settled on investing both in a geothermal system for my home, and shares in geothermal companies.
